The purpose of the report was to examine the components which have resu1ted in the establishment and maintenance of nuisance bear populations (i.e., the interaction between bears and a food supply generated by man's activity), and the management strategies which may be implemented to reduce the...

The workshop recorded in these proceedings was organized by the Alberta Reclamation Research Technical Advisory Committee as the first step in developing a Native Shrub Research Program for reclamation. While the importance of a detailed literature survey was recognized and is presently...

Two sites have been established for the study of stored peat. These are located at Evansburg ; Alberta and on the Syncrude Canada Ltd. lease at Mildred Lake, Alberta. Fibric and mesic moss peat and fen peat have been investigated in terms of their physical, chemical and microbiological...

The drainage system of the study area consists of a number of rivers draining from the west and from the east into the Athabasca River north of Fort McMurray, as well as a few rivers which join the Athabasca near Fort McMurray and drain areas to the south and east. Runoff from within the study...

Properties of stored peat were studied at sites near Evansburg, Alberta, and on the lease of Syncrude Canada Ltd. at Mildred Lake, Alberta. Physical, chemical, and microbiological properties of stored materials were compared with those of fibric moss peat, mesic moss peat, and mesic fen peat...

Sixteen, undisturbed, 5-hectare, permanent plots dominated by Pinus banksiana (jack pine) were established along an impingement gradient of atmospheric emissions from oil sands processing plants north of Fort McMurray in northern Alberta in August of 1981. Four plots were burned over by wildfire...

This report overviews major water quality patterns and trends for the Athabasca River and its major tributaries. In doing so it compares water quality data with surface water quality objectives, identifies spatial and temporal patterns, defines major factors affecting water quality,...

The heavy oils produced from the Alberta oil sands contain cyclic organic compounds together with sulphur and nitrogen. Upon thermal treatment they have the potential to form carcinogenic, mutagenic, and toxic compounds. Recovery of oil by in-situ combustion processes, such as the Combination of...

The calibrated DOSTOC, NUSTOC and UNSTOC models from 1989 were used effectively to simulate measured 1990 Athabasca River water quality. Changes in effluent loadings at the two pulp mills and an increase in river flows in the lower Athabasca Basin accounted for some noticeable improvements in...
